        private void Form2_Load(object sender, EventArgs e)
        {
              this.treeView1.Nodes.Add("root1");
            this.treeView1.Nodes.Add("root2");
            this.treeView1.Nodes.Add("root3");
            this.treeView1.Nodes.Add("root4");
            this.treeView1.NodeMouseClick += new TreeNodeMouseClickEventHandler(treeView1_NodeMouseClick);
        }        void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
        {
            //throw new NotImplementedException();
            e.Node.Nodes.Add("son1");
            e.Node.Nodes.Add("son2");
            e.Node.Nodes.Add("son3");
